to be honest i dont wanna make swing changes to accommodate that in addition to working hard on something as it is and i dont care about digging because once the ball is gone how much it digs is irrelevant and if it digs before the impact well, thats completely different problem then. love my range practice despite mats and all, range rat i guess so if anything i would rather have more of it not less. in any case i dont have that much of angle anyway, cant recall exactly but its in -4-5 range for 6 iron i think, going shallower would be pretty much swiping it and while 100% agree that it would sure be great for preventing strain when hitting tons of balls it just not something i wanna do.
There isn't one way to play golf for sure. It's whatever works and doesn't cause too much injuries whether to the wrist, elbow, shoulder or back.
